Green Star – Design & As Built

Green Star - Design & As Built is a new generation Green Star rating tool that will assess the sustainability of building design and construction. It will be able to assess most building uses in Australia with the exception of single-unit dwellings (BCA Classes 1a and 1b) and will cover single- and mixed-use buildings.

Green Star - Design & As Built is being developed in response to:

The feedback we have received from industry about the current suite of Green Star rating tools for design and construction via satisfaction surveys, detailed stakeholder interviews and internal and external scoping workshops

The need to continue and build upon the improvement outcomes delivered as part of our Green Star Revolution program of works in 2012/13

The learnings from the development of 12 Green Star - Custom rating tools for the design and construction of a diverse range of building types

The development of the Green Star - Communities, Green Star - Interiors and Green Star - Performance rating tools

The priorities and outcomes identified within the GBCA's 2013-2018 Strategic Plan.

Green Star – Design & As Built is more than just an amalgamation of the existing rating tools for the design and construction of buildings. It will aim to address new sustainability issues, and reflect current industry best practice. It will be delivered via an online platform that will host all technical content and information and ensure a streamlined submission process.

Green Star - Design & As Built will be designed to reduce the cost of certification while also encouraging innovation and world leadership in the delivery of sustainable outcomes for our built environment.

The development process for Green Star - Design & As Built is scheduled to take place from April 2013 to August 2014. It is expected that a first draft of all credits will be released for public comment in April 2014. Once draft credits are released, stakeholders will be invited to provide feedback on all the technical details and approach taken to achieving best practice sustainable outcomes.

It is currently expected that Green Star – Design & As Built rating tool will be available for use by project teams in late 2014.

Project drivers

The need to update

Over the past ten years, the GBCA has developed a range of sector-based Green Star rating tools in consultation with industry to assess the sustainable design and construction of buildings. Improvements upon the first rating tools have informed the development of more recent rating tools such as Green Star - Public Building, but it is recognised that the older rating tools within the suite are now in need of an upgrade.

New definitions of standard practice

Industry practices have progressed, many sustainable building elements and approaches have become standard practice. Increased expectations of what quality buildings should deliver, increased legislative requirements and improved building standards have all contributed to the changing definitions of 'standard practice' and subsequent industry-wide improvements to the way buildings are designed and delivered.

An expanded definition of sustainability

In addition to improvements to standard practice, the definition of what constitutes 'world leadership' in building design and construction has also expanded to encompass many socio-economic considerations that were not addressed within the original Green Star Design and As Built rating tools. Some of these issues are already being explored through Green Star – Communities, as well as via the recent expansion of the Green Star Innovation category. In line with these changes to the definition of 'best practice' sustainability, it is expected that some social and economic sustainability-focussed credits will be incorporated into the Green Star - Design & As Built rating tool.

Incorporating improvements and suggestions

The GBCA has received substantial feedback and suggestions for improvements to benchmarks, credits and delivery approaches via our annual Green Star satisfaction surveys, review panels, stakeholder interviews and internal and external workshops. The collective industry experience gained from the certification of over 600 Green Star projects has also provided us with a wealth of information and alternative approaches to reducing environmental impacts via the formal Green Star process of Credit Interpretation Requests (CIRs) and Technical Clarifications (TCs), and through informal anecdotal feedback.

Learning from Green Star - Custom

The Green Star – Custom process has also provided us with further feedback and understanding as it has allowed us to develop Green Star rating tools to rate the sustainable design and construction of a number of complex or a-typical building types, including quick service restaurants, supermarkets, above-ground train stations, hotels and retirement villages.

A universal approach

Following the development in recent years of our 'new generation' Green Star rating tools; Green Star – Communities, Green Star – Interiors and Green Star – Performance, we have received feedback that a cross-sector approach to rating tool development is preferred by the majority of industry stakeholders. That is, rather than developing rating tools based on a particular sector or market (office or education for instance), most stakeholders prefer that our rating tools are developed to be 'universal'; rating many types of buildings, communities, fitouts or existing buildings in operation, irrespective of their end-use, as shown here:


11

Reducing costs

The GBCA has received consistent feedback from project teams, building owners and developers that the cost of certifying projects using the current Green Star Design and As Built rating tool buildings is high and in some instances preclusive. As a result, we're conducting research and interviews to try to pinpoint where costs might be reduced during the development of Green Star – Design & As Built, without compromising on the rigor of the rating tool or the sustainability outcomes achieved.

Tell us what you think:

Do you have any other suggestions about these or other project drivers for Green Star - Design & As Built?


12

Delivering on project outcomes: scope and approach

Green Star - Design & As Built will assess the design and construction attributes of buildings of all uses and sizes

Green Star - Design & As Built will assess the design and construction of most building types via a 'universal' approach, ie: one cross-sector rating tool. The key exception identified to date is single unit dwellings or townhouses where no common areas exist (BCA Classes 1a and 1b).

Examples of building types covered by this rating tool include currently addressed sectors such as education facilities, healthcare facilities, industrial buildings, commercial office buildings, retail centres, public buildings, and multi-unit residential. In addition, it will have the capacity to assess sectors and building types that are not covered by the existing Green Star rating tools for design and construction, such as student housing, restaurants and hotels. Green Star - Design & As Built will also assess buildings that are undergoing significant refurbishment (buildings where works undertaken render more than 50% of the building unable to be occupied under normal operating conditions).

Green Star - Design & As Built will address buildings delivered as 'shell and core', 'integrated fitouts' and ‘conventional delivery’. We define these terms as follows:

• Shell and Core: Finishes and services are applied to common areas only. Spaces are delivered with no ceilings, floor coverings, lighting systems and partition walls, and ducts from air supply and return risers finish within 1m of the face of the riser. This is common in industrial, retail centres and retail buildings.

• Conventional Delivery: Finishes and services are applied to common areas. Occupied areas are delivered with ceilings, floor coverings, finishes and a standard design for supply and return ducts, with a lighting system installed on a grid. Typically in the case of commercial office buildings, the tenant comes in and adjusts the delivered services and finishes. This delivery method is common for commercial office buildings or spaces that will be tenanted.

• Integrated Fitout: Where the design and construction brief addresses, in addition to typical building elements, ceilings, floor coverings, lighting systems, mechanical, electrical and hydraulic services, partition walls, finishes, and fitout elements to all (or most) areas. In most cases, the design and construction involves significant coordination with the client or tenant. This is common for education, hospitality and healthcare facilities, but is also seen in premium grade commercial office buildings.

Green Star Design & As Built will assess buildings of all sizes and complexities.


What types of buildings do you think should or should not be eligible for assessment under the new Green Star - Design & As Built rating tool?

http://svc136.bookeasy.com/accom_result1/mercure-kooindah-waters-golf-spa-resort/


13

Should refurbishments be eligible for assessment under this rating tool?

How should 'significant refurbishments' be defined?

Are the definitions of 'shell and core', 'integrated fitout' and 'conventional delivery' still appropriate today? If not, why not and what other definitions should be considered?

Considering the universal application of the rating tool, should Green Star - Design & As Built address the full scope of deliveries, from shell and core to integrated fitouts? What are the benefits or drawbacks of this approach?

Do you think there should be a size limit for the buildings that can be assessed by Green Star - Design & As Built?


14

Please provide any additional feedback on the proposed scope of assessment here

Green Star - Design & As Built will integrate and align with Green Star – Communities, Green Star – Interiors and Green Star – Performance

The new Green Star - Design & As Built rating tool will integrate and align with the Green Star – Communities, Green Star – Interiors, and Green Star – Performance rating tools. Green Star - Design & As Built will:

• Reduce documentation and reward and buildings that build within Green Star – Communities rated sites where applicable

• Encourage and make easy the transition from an attributes-only sustainability assessment to one that also incorporates sustainable performance in operation, in alignment with Green Star – Performance.

• Facilitate the development of fitouts that comply with the requirements of Green Star – Interiors within the Green Star - Design & As Built certified projects and minimise the challenges and risks associated with achieving a subsequent Green Star - Interiors rating.


What other opportunities for alignment of the rating tools exist? Do you have any suggestions for how alignment can be increased to ensure better and more consistent project and sustainability outcomes?

What other challenges or frustrations that project teams face when progressing their project through the different rating tools exist? How could these challenges or frustrations be minimised through Green Star - Design & As Built ?


15

Green Star - Design & As Built will provide a pathway for ensuring design attributes are implemented throughout construction

The Green Star rating tools for building design have been instrumental in encouraging Australia's property and construction industry to design and build green over the past ten years. Green Star - Design ratings have encouraged project teams to consider sustainability from the initial stages of project development and have provided a set of holistic, best practice benchmarks to guide the design approach of project teams.

The current Green Star - Design rating is intended to serve as guide and provide the groundwork for the eventual construction of a building, which will then go on to achieve a Green Star – As Built certification to demonstrate that the sustainability objectives and potential of the sustainable design has been fulfilled. The ‘As Built’ rating then provides a foundation for the sustainable operation of the building, which can be assessed and certified using Green Star - Performance.

Currently, a building can be awarded a Green Star – Design rating, a Green Star – As Built rating, or both. The ratings are achieved through two separate assessments, and some of the same information must be provided for a building's ‘As Built’ assessment as is provided for its 'Design' assessment. Recent amendments to the current Green Star rating tools have introduced some 'deemed-to-satisfy' criteria in an effort to streamline the transition from Design certification to As Built assessment and reduce the duplication of time and effort by project teams. It is intended that this approach should continue, and that the Green Star - Design & As Built rating tool will be developed in such as way as ensures a smooth transition between assessments.

The current Green Star rating tools for building design award ratings on the basis of documentation provided by project teams at the tender stage. That is, the documentation needs to show building elements have been designed to a high degree of certainty. If a form of assessment at the design stage should exist, it is proposed that the requirements for a Green Star - Design rating are relaxed so that it becomes a rating signalling commitment, rather than achievement.

In 2012, and after extensive stakeholder research, the GBCA modified the terms of achievement for Green Star - Design ratings, introducing a 24 month time limit for projects that achieve Green Star – Design certification. This change aimed to encourage projects to follow through and demonstrate that the sustainability 'commitments' of the design have been delivered at the construction stage. Green Star - As Built ratings currently have no time limit on their validity and Green Star building owners can therefore use their Green Star certification to market their project on an ongoing basis.

In an effort to expand the reach and influence of Green Star and its relevant benchmarks, recent feedback indicates that there would be support for an expansion of Green Star Design & As Built certification to all Star levels; from 1 Star Green Star through to 6 Star Green Star. Such a change would allow stakeholders, who have achieved a 3 Star Green Star certified rating (representing 'Good Practice' in sustainable design or construction) to market their building as such.


Do you think that there is still a need to offer some form of assessment and certification for building design? Why, why not?


16

Which of the following statements do you agree with?

Green Star - Design ratings should continue to be awarded without a requirement for a subsequent As Built rating. The current time limit of two years on the validity of Green Star ratings is a sufficient measure to address the issue of lack of delivery.

Yes N o

Green Star - Design ratings should be awarded only upon the condition of the future achievement of an As Built rating.

Yes N o

There should be no Green Star - Design rating. It should be replaced with a design stage pre-certification to assess whether the project is on course to achieve an As-Built rating. This pre-certification should not allow project teams to market their project as Green Star - Design certified.

Yes N o

There should be no Green Star assessment at the design stage

Yes N o

Please provide further comments or feedback to support your view on the future of Green Star - Design ratings below

What is the relevant purpose of a 'Design' rating? Would a commitment suffice? Should it be addressed at the design brief stage? Schematic design? Other?

Do you agree with the current approach to design ratings whereby a time limit applies? If so, is 24 months still an appropriate period? Should a time limit exist for Green Star - As Built ratings?


17

Do you believe that the rating scale for Green Star - Design & As Built certified ratings should be expanded to include 1 Star - 3 Star ratings?

Do you believe there is a need to recognise achievements in excess of 6 Stars in some way?

Green Star - Design & As Built will provide a simpler, more user-friendly and cost-effective user experience

The Green Star - Design & As Built rating tool and submission process will be delivered entirely online. This means that there will be no traditional technical manual or scorecard, and that technical content and submission guidelines will be integrated within the rating tool. Green Star - Design & As Built will be created within a similar online system to the Green Star – Performance PILOT. The online platform will:

• Streamline the submission processes, making it easy for users to submit the required inputs

• Streamline the certification process, utilising upload facilities to reduce the amount of documentation required for a certified rating

• Reduce the amount of time required for project certification, reducing costs

• Allow easy access and updates of all technical documentation related to assessment methodology, including manuals and guides

• Allow other resources such as standards, case studies and other external resources to be directly referenced within the assessment methodology

See Appendix 3 for screenshot examples of the Green Star – Performance online interface upon which the Green Star - Design & As Built online system will be modelled.

The current method of delivering Green Star rating tools means that a significant amount of technical guidance, clarifications and corrections must be delivered independently of the Technical Manual. Moving our rating tools to an online delivery system should allow for more frequent updates, improving the accuracy and integration of technical information. It is proposed the new rating tool be updated at least once a year to incorporate relevant amendments, with a two year review cycle for major amendments and updates.


18

In addition, the GBCA hopes to work with software or other service providers to integrate enhanced features into the online rating tool system, that can assist project teams with:

• Managing the project delivery

• Collecting and coordinating documentation

• Improve building design through modelling practices that align with Green Star requirements.

We are currently scoping how best to work with software and service providers and will be engaging in consultation with interested parties in late 2013 and early 2014.


What features should be included as part of the Green Star - Design & As Built online system?

\

Do you agree with the proposed timeframe/schedule for updates to the rating tool? If not, what is your preferred schedule for updates?

Green Star - Design & As Built will help to ensure that Green Star remains the rating system of choice for the built environment by redefining current best practice and promoting innovation

Over the past few years, our work with a range of organisations to develop Green Star – Custom rating tools has helped us to identify a range of potential improvements that can be integrated into the Green Star - Design & As Built rating tool, such as the removal of outdated credits like 'High Frequency Ballasts' and 'Insulant ODP'. Feedback from project teams also indicates the need to revise approaches in the 'Land Use and Ecology' category and to develop common methodologies for assessing greenhouse gas emissions and potable water use. Finally, recent discussion papers on Construction and Demolition Waste and Material Life Cycle Impacts indicate the industry is ready to explore and embrace new impact reduction approaches.

The development of Green Star - Design & As Built rating provides an opportunity to redefine Australian 'best practice' for sustainable design and construction and explore opportunities for expanding the rating tool's scope of assessment beyond environmental impacts to incorporate social and economic sustainability impacts such as adaptation and resilience, cultural heritage, employment creation and community engagement.


19

A high-level roadmap on the potential approach to credit development is included at Appendix 2. The roadmap is a snapshot of our current thinking, and will not reflect necessarily reflect the final Green Star - Design & As Built rating tool.

The rating tool roadmap proposes a number of alternative performance options for a variety of credits. These are shown as a ‘performance path’ surrounding a ‘prescriptive path’. Currently, alternative performance path options are expected to be adopted for ‘Greenhouse Gas Emissions’, ‘Potable Water’, ‘Material Lifecycle Impacts’, ‘Carbon Emissions from Transport’, and ‘Land Use and Ecology’. For these impact issues, a project may, for example, be able to demonstrate compliance solely through ‘Carbon Emissions from Transport’ or via three credits: ‘Impacts from Car Parking’, ‘Alternatives to Private Transport’ and ‘Commuting Mass Transport'. The performance approach would provide more flexibility to project teams in demonstrating compliance, allowing them to prove compliance in ways that are most relevant to their projects. Meanwhile, project teams seeking a simpler, more conservative path will be able to address the prescriptive options

As part of our broader Green Star 2014 program of works, the Green Star Innovation category been recently relaunched in order to encourage and direct investment in new sustainable solutions, and assist project teams working with the current suite of Green Star rating tools to embed innovative sustainable goals and outcomes into their projects as early as possible by taking Innovation Challenges. There maximum number of points available within the Innovation category has increased from 5 to 10 points and the category has been expanded to address new social and/or economical issues. The changes to the Green Star Innovation category are allowing us to test new approaches and credits, which will be incorporated into the development of Green Star - Design & As Built where appropriate.


Please provide comments on the contents and approach of the roadmap directly by marking it up using Acrobat Reader.

While details about scope of specific credits are currently limited, please provide feedback on the following:

Should the scope of the rating tool be limited to environmental issues, or should this scope be expanded to include socio-economic sustainability impacts?

Are there any issues or credits that you think should not be included in the new Green Star - Design & As Built rating tool because they are now just 'business as usual'? Do you believe they should be removed entirely, or should they become minimum requirements for other credits (Eg. High frequency ballasts could become a requirement for other lighting credits)?


20

Are there any other issues or impacts that are not covered by the roadmap that should be considered for inclusion in the new rating tool? If so, please provide links to resources that will assist the Technical Advisory Group (TAG) in assessing the relevance of such issues.

Currently, there are only two minimum requirements in the Green Star rating tools for design and construction - the Greenhouse Gas Emissions Conditional Requirement and the Land Use and Ecology Conditional Requirement. Should there be any additional minimum requirements required for the achievement of particular Star ratings? For example, should a mandatory Greenhouse Gas Emissions score be achieved in order for a project to be awarded a 5 or 6 Star Green Star certification?

Are there any other opportunities for providing performance or prescriptive paths to address the issues highlighted in the roadmap? If so, please provide details below.

Green Star - Design & As Built will allow issues, features and design solutions to be clearly and accurately compared through the implementation of a revised weighting system

As part of the development project for Green Star – Design & As Built, the current Green Star weighting system will be reviewed. Key reasons for this review include:

• The current system of weighting can make it difficult to compare the impacts that one solution will have across multiple categories, making communication difficult between all relevant parties and requiring significant expertise to interpret.

• The current weighting system varies across different building sectors which does not allow for a clear comparison across different building types, and makes the assessment of mixed-use buildings complex.


21

• The current weighting system is state based and does not account for the significant climate zone variations within each Australian state and territory. Similarly, the current system means that cities that lie within close proximity, share the same or similar climate and even the same infrastructure, but that lie within different states may be awarded different weighted points.

Feedback to date indicates that current weightings system should be radically simplified. The current preference is to simplify the weighting system in a manner similar to the Green Star – Performance and Green Star – Communities rating tools, where 1 point is comparable across categories. The issue of regional or climatic variations can then be resolved through the Innovation category or variations within credits themselves.


Should the current system of weighting, whereby different states and territories have different weightings remain? If so, how could climate factors and power supply be accounted for within the rating tool?

Should one point in one category be equal to one point in another category, i.e. no weightings?


22

Delivering on project outcomes: development and testing

The GBCA aims to have all revised and new credits for Green Star – Design & As Built available in draft format for public comment and feedback by April 2014. Once these draft credits are released, project teams who are using the current rating tools may choose to test these new draft credits contribute their feedback to the development process. This approach will allow for ‘beta testing’ of the new rating tool prior to its full release in August/October 2014. This would also mean that the rating tool would not be subject to a formal PILOT phase, as has been the customary approach for new Green Star rating tools in the past. This means that the market will be able to reap the benefits of the new Green Star - Design & As Built rating tool sooner.


Do you agree with the 'beta testing' approach to development and testing? If not, please provide details of the alternative approach you would suggest.

Delivering on project outcomes: other feedback or suggestions

The Green Star rating tools are only successful insofar as they meet and respond to the needs of the market. The GBCA welcomes your feedback and suggestions on any other aspects of Green Star - Design & As Built's scope, content or development, and how we might can use this development phase to address issues within the current Green Star rating tools for design and construction or improve the user experience.


Please provide your feedback or suggestions on any additional issues or opportunities that should be addressed or considered during the development and review of Green Star - Design & As Built.
